CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U.S.C. § 119(e) of co-pending U.S. Provisional Patent Application No. 62/823,175 filed on Mar. 25, 2019, the entire disclosure of which is hereby incorporated by reference.

BACKGROUND

The disclosure generally relates to the field of electrical installations, more specifically, electrical conduits, particularly, cable duct assemblies (e.g., cable ducts, modular cable duct assemblies). Cable duct assemblies are used to protect, route, and organize elongated cables, such as fiber optic cables and electrical cables (e.g., power cables, communication cables, conductors), inside electrical panels, electrical cabinets, and other hard-to-reach applications. Some cable duct assemblies include a base plate configured for mounting to a surface, a pair of opposing sidewalls defining a passageway therein, and a cover plate attaching to the sidewalls. The cover plate encloses the passageway.

In some applications, the base of a cable duct assembly is mounted on a non-horizontal surface, such as a vertical wall surface. In such a configuration, the weight of the cables carried in the passageway may act as a load that pushes downwards on the lowermost sidewall of the cable duct assembly, potentially causing the cover plate to disconnect. The disconnection of the cover plate could result in one or more of the cables spilling out of the passageway otherwise provided by the cable duct assembly.

DETAILED DESCRIPTION

The details of one or more aspects of cable duct assemblies and cable duct assembly components are described in this disclosure. Cable duct assemblies and cable duct assembly components made in accordance with this disclosure have particular application in open environments, electrical cabinets, and electrical panels to protect, route, and organize cables, particularly in applications that are in hard-to-reach or confined spaces in which the cables require protecting.

A first cable duct assembly 100 is illustrated in FIGS. 1A-6C, a second cable duct assembly 200 is illustrated in FIGS. 7A and 7B, and a third cable duct assembly 300 is illustrated in FIGS. 8A, 8B, 8C, 8D, and 9. These Figures illustrate a cable duct assembly that includes a cover plate arranged opposite a base plate and a pair of sidewalls arranged opposite one another. For example, FIGS. 1A-6C illustrate a cable duct assembly 100, which includes a cover plate 110 arranged opposite a base plate 130 and a pair of sidewalls 150 arranged opposite one another (e.g., a first sidewall 151 arranged opposite a second sidewall 172).

The base plate 130 forms the base of the cable duct assembly 100. The base plate 130 may define at least one sidewall connector (e.g., sidewall connector 132, sidewall connector 142) that is configured for connecting with a sidewall 150 (e.g., first sidewall 151, second sidewall 172). For example, in the first cable duct assembly 100, a first sidewall connector 132 and a second sidewall connector 142 are illustrated, where the first sidewall connector 132 is spaced apart from and generally parallel to the second sidewall connector 142. In the first cable duct assembly 100, the first sidewall connector 132 engages with (e.g., snaps into) the first sidewall 151, and the second sidewall connector 142 engages with the second sidewall 172.

The sidewall connector may include an inner base rail spaced apart from an outer base rail to define an open-ended locking channel that is configured for receiving a sidewall stem of a sidewall therein. For example, as illustrated in FIG. 2B, the sidewall connector 132 may include an inner base rail 138 spaced apart from an outer base rail 140 to define an open-ended locking channel 134 that is configured for receiving the sidewall stem 152 of a sidewall 151 therein. As illustrated in FIG. 2B, the inner base rail 138 may include an inner locking flange 139 that extends into the locking channel 134, and the outer base rail 140 may include an outer locking flange 141 that extends into the locking channel 134.

The base plate 130 may include a base extension 148 that extends past the distal side of the sidewall connector (e.g., first sidewall connector 132, second sidewall connector 142). The base extension 148 stiffens the outer base rail (e.g., outer base rail 146) in relation to the base plate 130, thereby preventing the outer base rail from rotating about the edge of the base plate 130. For example, in FIG. 8D, the load on the sidewall 150 results in the outside of the sidewall stem 152 and/or the outside of the lower portion of the sidewall 150 contacting and applying a force to the outer base rail 140 that is translated (transferred) to the base extension 148 and to the connected surface 8. During such a situation, while the outside locking recess 170 may move out of engagement with the outer locking flange 141, the inside locking recess 168 remains engaged with the inner locking flange 139 and the sidewall stem 152 is retained within the locking channel 134, that results in the maintenance of the connection between the sidewall stem 152 and the sidewall connector 132.

The cable duct assembly 100 may include one or more pivot connections (e.g., first pivot connection 133, second pivot connection 135) that pivotally connect a sidewall to a respective sidewall connector. For example, as illustrated in FIGS. 4 and 8A, through the interaction between the sidewall stem (e.g., sidewall stem 152) inserted into the sidewall connector (e.g., first sidewall connector 132), the inside locking recess 168 receives the inner locking flange and the outside locking recess 170 receives the outer locking flange 141, as illustrated in FIG. 2B, and the sidewall is able to pivot at its attachment with the base plate 130, as illustrated in FIG. 8B.

As a result of the load exerted on the lower sidewall, illustrated in FIG. 8A, the cable duct assembly 300 moves as a four-bar linkage, with rotation at the first hinge mechanism 111 and the second hinge mechanism, and that pivots at the first pivot connection 133 and the second pivot connection 135. As illustrated in FIG. 8D, the load on the first and second arms of the sidewall 151 may cause rotation of the first pivot connection 133, which brings the snap reinforcement 192 into contact with the inner locking flange 139, thereby locking the sidewall stem 152 within the sidewall connector 132 of the base plate 130.

The base plate 130 is configured for attaching to a surface 8, as illustrated in FIG. 8A. While FIG. 8A illustrates a vertical wall surface, in other aspects the surface may be differently oriented. In FIG. 8A, a plurality of fasteners 137 are inserted through slots 136 (illustrated in FIG. 2A) to attach the base plate 130 to the surface 8.

The cable duct assembly 100 further includes a plurality of sidewalls 150 arranged opposite one another (e.g., a first sidewall 151 arranged opposite a second sidewall 172), as illustrated in FIG. 2A. The sidewalls 150 are configured to connect between the base plate 130 and the cover plate 110. When connected with the base plate 130, the sidewalls 150 define a passageway 102 that is configured for receiving one or more elongated objects, such as cables 2, therein.

FIG. 1A illustrates a pair of sidewalls 150 (e.g., first sidewall 151, a second sidewall 172) and FIG. 3 is a side view of a sidewall 150 of a cable duct assembly 100. In configurations, the sidewall 150 connects the base plate 130 to the cover plate 110 and is located between the base plate 130 and the cover plate 110. A sidewall 150 may include a sidewall stem that is configured for connecting with a base plate 130 at a sidewall connector (e.g., first sidewall connector 132, second sidewall connector 142) and at least one arm. A sidewall 150 may include at least one first arm (e.g., first arm 154, first arm 155) and at least one second arm (e.g., second arm 174, second arm 175).

The sidewall stem (e.g., sidewall stem 152, sidewall stem 171) may include a distal end that is configured for receipt into a locking channel (e.g., locking channel 134 of a first sidewall connector 132, locking channel 143 of a second sidewall connector 142). At least one arm (e.g., first arm 154, second arm 174) extends from the sidewall stem of the sidewall 150. The sidewall 150 may include at least one first arm and at least one second arm. For example, the first sidewall 151 illustrated in FIG. 1A includes a plurality of first arms 154 and a plurality of second arms 174. A sidewall 150 may include a plurality of first arms and a plurality of second arms that are arranged in a pattern of alternating positions along a length of the sidewall stem, such as is illustrated in FIGS. 1A, 2A, and 3. In other aspects, at least one of the sidewalls 150 may include any combination and order of first arms 154 and second arms 174 along a length of the sidewall stem. The second sidewall 172 may include a plurality of first arms and a plurality of second arms, as is illustrated in FIG. 1. The second sidewall 172 may include a plurality of first arms and a plurality of second arms that are arranged in a pattern of alternating positions along a length of the sidewall stem 171, such as is illustrated in FIG. 1. The first arms and second arms may be positioned in any combination and/or order along the length of the sidewall stem 171.

While in aspects, the first sidewall 151 and the second sidewall 172 may be configured differently, in the cable duct assembly 100 illustrated in FIGS. 1A, 2A, and 3, the first sidewall 151 and second sidewall 172 are generally identical to one another and, as positioned in the base plate 130, are mirror images of each other. As such, a description of features of the first sidewall 151 can be extended to equivalent features on the second sidewall 172.

The sidewalls 150 are configured for pivotal connection with the base plate 130. The first sidewall 151 may be configured to pivotally connect with the base plate 130 through a first pivot connection 133, and the second sidewall 172 is configured to pivotally connect with the base plate 130 through a second pivot connection 135.

The sidewalls 150 are configured to hingedly connect with the cover plate through hinge mechanisms. The first sidewall 151 may be configured to hingedly connect with the cover plate 110 at a first side 124 through a first hinge mechanism 111, and the second sidewall 172 is configured to hingedly connect with the cover plate 110 at a second side 126 through a second hinge mechanism 121.

As illustrated in FIG. 3, the first arm 154 extends from a top side of the sidewall stem 152 to a first arm end 156. The first arm end 156 may include a lobe mechanism 158 (also illustrated in FIGS. 6A-6C) that is configured for rotational connection with a first saddle channel 112 of the cover plate 110 to form a first hinge mechanism 111. As illustrated in FIGS. 6A-6C, the first lobe mechanism 158 includes a rounded outer lobe portion 160 and a rounded inner lobe portion 162. The rounded outer lobe portion 160 is configured to rotatably engage the first saddle channel 112 and to releasably secure the cover plate 110 to the sidewall 150.

As illustrated in FIG. 6B, the rounded outer lobe portion 160 may include a first radius R1, and the rounded inner lobe portion 162 may include a second radius R2. In aspects, the first radius R1 is greater than the second radius R2. This difference in radii allows, in a first configuration (e.g., the configuration illustrated in FIG. 5C) the rounded outer lobe portion 160 to be inserted into the saddle channel 112 and then permits, in a second configuration, the rounded outer lobe portion 160 to rotatably engage the saddle channel 112.

The first lobe mechanism 158 may further include a detent step 164 (anti-rotation detent) defined intermediate the rounded outer lobe portion 160 and the rounded inner lobe portion 162, as illustrated in FIG. 6B. The detent step 164 is configured to engage a socket projection 119 defined in the second flange 116 of the first saddle channel 112, and thereby prevent over-rotation of the cover plate 110 relative to the first arm 154 beyond an angular limit (e.g., 90°), for example as illustrated in FIG. 6A.

The second arm 174 extends from the top side of the sidewall stem 152 to a second arm end. The second arm 174 may include a rotation limiter 178 that is configured to engage the first saddle channel 112 of the cover plate 110. The rotation limiters 178 may include a catch portion 190 that is free-floating in a first mode and are configured, in a second mode, to engage the first saddle channel 112 and limit rotation of the first saddle channel 112 relative to the rotation limiter 178 and the arm. In aspects, such as is illustrated in FIG. 5B, the rotation limiters 178 are generally C-shaped, having a front jaw 180 and a rear jaw 182. A recess 184 is defined between the front jaw 180 and the rear jaw 182.

The first flange 114 may include a cover hook portion 115 that extends into the saddle socket 118. The front jaw 180 is configured for receipt into the saddle socket 118, and the recess 184 is configured to receive the cover hook portion 115 therein. As a result, the rotation limiter 178 is configured to engage the saddle socket 118 at the cover hook portion 115 to limit the rotation of the first saddle channel 112 relative to the rotation limiter 178 and the arm.

The second arm 174 may also include an inwardly extending deflector portion 186 that extends into the passageway 102. The deflector portion 186 extends into the passageway 102 farther than the inward side 166 of the first arm 154 extends so that when the cable duct assembly 100 is mounted in a horizontal orientation, the deflector portion 186 is configured to receive a load from the cable 2, whereas the first arm 154 does not so contact cable 3.

The arms (e.g., first arm 154, second arm 174) may include a break-off point near the base plate 130 for routing cables 4 through a sidewall 150. FIGS. 3, 7A, and 7B illustrate that at least one of the first arm 154 or the second arm 174 includes break-off points (e.g., score line) at or adjacent the connection between the respective arm and the sidewall stem 152. For example, in FIG. 3, a first arm 154 is illustrated as having a break-off point 194 defined at the connection between the first arm 154 and the sidewall stem 152, and the second arm 174 is illustrated as having a break-off point 196 defined at the connection between the second arm 174 and the sidewall stem 152. In aspects, the break-off points (e.g., break-off point 194, break-off point 196) may include a chamfered neck, for allowing the arm to be easily twisted off and removed from the sidewall stem, and to provide an additional space for cables to run through the sidewall, for example, as illustrated in FIGS. 7A and 7B. When an arm is twisted off in such a fashion when the sidewall 150 is installed on the base plate 130 by insertion of the sidewall stem 152 into the sidewall connector 132, the break-off point is located below the top of inner base rail 138 and outer base rail 140, leaving no material sticking up (e.g., a sharp vestige) above the base rails that could catch on and/or damage cables routed through the sidewall, as illustrated in FIGS. 7A and 7B.

The sidewall 150 may include one or more nodules 128 that extend from an inside surface. The nodules 128 are configured for receipt into the upper portion of the sidewall connector (e.g., sidewall connector 132). The nodules 128 are configured to keep the sidewall 150 perpendicular to the base plate 130 (e.g., when horizontally mounted).

As illustrated in FIG. 1A, the sidewall stem 152 may include at least one of a snap reinforcement 192 on a first side of the sidewall stem 152 and a snap cutout 198 on a second side of the sidewall stem 152. During sidewall stem insertion into a sidewall connector, friction may occur between the rails (e.g., inner base rail, outer base rail) of the sidewall connector and the wall stem. In the cable duct assembly 100, the sidewall stem (e.g., sidewall stem 152) is configured to be inserted into the sidewall connector (e.g., first sidewall connector 132) so that the inside locking recess 168 receives the inner locking flange and the outside locking recess 170 receives the outer locking flange 141, as illustrated in FIG. 2B. Through such a configuration, the insertion force required due to friction is minimized due to the small surface contact area.

A sidewall 150 may include at least one snap reinforcement 192 on the first side of the sidewall stem 152 directly opposite a snap cutout 198 on the second side of the sidewall stem 152. FIG. 1A illustrates four snap reinforcements 192 along the sidewall stem 152 and four snap cutouts 198 on the second side of sidewall stem 171. The snap reinforcements and/or snap cutouts help maintain snap strength after multiple sidewall 150 insertions and extractions from a sidewall connector. The snap reinforcement 192 defines an inside locking recess 168, and the opposite side of the sidewall stem 152 defines an outside locking recess 170. The inside locking recess 168 is configured to engage the inner locking flange 139, and the outside locking recess 170 is configured to engage the outer locking flange 141 when the sidewall stem 152 is inserted into the locking channel 134. Such a connection defines the pivot connection (e.g., first pivot connection 133, second pivot connection 135) described herein.

The cover plate 110 is configured to attach to the sidewalls 150 and to enclose the passageway 102, as illustrated in FIG. 4. In such a configuration, one or more objects (e.g., cables 2, 3) are retained within the passageway 102 of the cable duct assembly 100.

As illustrated in FIGS. 1A-6C, the cover plate 110 has a first side 124 and a second side 126. The cover plate 110 may include at least one saddle-shaped hinge feature, hereinafter referred to as the saddle socket, that is configured to engage a sidewall 150 at a sidewall arm end. For example, in the cable duct assembly 100 illustrated in FIG. 2A, the cover plate 110 includes a pair of saddle sockets (e.g., first saddle socket 118, second saddle socket 120). The first saddle socket 118 may extend along an underside of the cover plate 110 is disposed adjacent a first distal edge of the cover plate 110 and the second saddle socket 120 extends along the underside of the cover plate 110 is disposed adjacent a second distal edge of the cover plate 110.

The first saddle socket 118 is configured to engage the first sidewall 151 at a plurality of first arm ends 156 and second arm ends 176, and the second saddle socket 120 is configured to engage the second sidewall 172 at a plurality of first arm ends 157 and second arm ends 177. As is illustrated in FIGS. 1A, 2A, and 4, the saddle sockets (e.g., first saddle socket 118, second saddle socket 120) may generally be identical to one another and, as positioned connected to the cover plate 110, may be mirror images of each other.

As illustrated in FIG. 1B, a saddle socket (e.g., saddle socket 118) may include an elongated first flange 114 (first flange 114) and an elongated second flange 116 (second flange 116). An elongated saddle channel 112 is defined between the first flange 114 and the second flange 116. The saddle socket 118 may extend along at least a portion of the length of the cover plate 110, as illustrated in FIG. 1A and FIG. 2A. The first saddle channel 112 may be configured to rotatably receive a plurality of lobe mechanisms 158 of the first arm ends 156, and a plurality of rotation limiting portions (e.g., rotation limiters 178) defined on the second arm ends 176. The lobe mechanism 158 is configured to rotatably engage a saddle socket (e.g., saddle socket 118). The lobe mechanism 158 may be configured so that a portion of the lobe mechanism 158 is received between the first flange 114 and the second flange 116 and into the saddle channel 112. The first saddle channel 112 may be configured to snap into place on the lobe mechanisms 158, and the lobe mechanisms 158 may retain the cover plate 110 on the cable duct assembly 100 when the cable duct assembly 100 is installed on a connected surface 8, such as is illustrated in FIG. 8A. In aspects, the lobe mechanisms 158 allow the cover plate 110 to rotate to 90° (as illustrated in FIG. 5A). As illustrated in FIG. 6B, the second flange 116 may further include a socket projection 119 that is configured to engage the detent step 164, described herein.

The saddle socket 118 may be configured to connect with at least one arm end (e.g., first arm end 156, second arm end 176) of a sidewall 150 to form a hinge mechanism (e.g., hinge mechanism 111, hinge mechanism 121) that pivotally connects the cover plate 110 to a sidewall 150. For example, as illustrated in FIG. 2A and FIG. 4, the saddle socket 118 is configured to receive first arm ends 156 of first arms 154 and second arm ends 176 of second arms 174 of a first sidewall 151 to form a first hinge mechanism 111. The cover plate 110 is configured to rotate relative to a connected first sidewall 151 through the first hinge mechanism 111 when the cover plate 110 is detached from a second sidewall. Likewise, the cover plate 110 is configured to rotate relative to a connected second sidewall 172 through a second hinge mechanism 121 when the cover plate 110 is detached from the first sidewall 151.

The saddle channel 112 may further include a guide ramp 117, for example, that extends from the second flange 116. The guide ramp 117 is configured to align at least one of the lobe mechanism 158 or the rotation limiter 178 for insertion into the saddle channel 112 during the installation of the cover plate onto a first sidewall and/or when closing the cover plate on a second sidewall, as illustrated in FIG. 5C. For example, as the cover plate 110 is brought into connection with the first arm ends 156 of the first arms 154 and second arms 174 of a sidewall 150, the guide ramp 117 guides the lobe mechanism(s) 158 and/or the rotation limiter(s) 178 towards the saddle channel 112, to enable the cover plate 110 to “snap” onto the lobe mechanism(s) 158.

In a cover-closed configuration (illustrated in FIG. 4), the cover plate 110 is hingedly connected, at a first side 124 and a second side 126, to a first sidewall 151 and a second sidewall 172 through a second hinge mechanism 121. In the cover-closed configuration, the first sidewall 151 and the second sidewall 172 are also pivotally connected to the base plate 130 at a first sidewall connector 132 and a second sidewall connector 142. In such a configuration, the cover plate 110 is able to move, relative to the first sidewall 151, second sidewall 172, and the base plate 130, through the hinged and pivot connections, as will be described in greater detail herein. The lobe mechanisms (e.g., lobe mechanism 158) on the arm ends retain the cover plate 110 when the passageway 102 of the cable duct assembly 100 is loaded with objects (e.g., cables 2, 3).

FIG. 2A illustrates a pair of sidewalls 150 (e.g., first sidewall 151, second sidewall 172) connected to the base plate 130, and the cover plate 110 is hingedly connected to a sidewall 150 (e.g., the first sidewall 151) through the first hinge mechanism 111. In such a cover-open configuration (illustrated in FIGS. 2A, 5A, and 6A), the cable duct assembly 100 defines a passageway 102 that is configured to receive one or more cables 2 (illustrated in FIG. 8A) or other objects therein. In the cover-open configuration, the cover plate 110 is configured to rotate about the first saddle channel 112 and/or the second saddle channel 122 to allow access to objects (e.g., cables 2 (illustrated in FIGS. 8A, 8C, and 8D)) stored within the passageway 102.

In the cover-open configuration (illustrated in FIGS. 2A, 5A, and 6A), the cover plate 110 is configured to pivot at the first side 124 about the first sidewall 151, when a second side 126 of the cover plate 110 is detached from the second sidewall 172. For example, FIG. 2A illustrates the first side 124 of the cover plate 110 attached to a first sidewall 151 but detached from a second sidewall 172. In such a configuration, a cable 2 (illustrated in FIG. 8A) or another object can be inserted into the passageway 102 defined through the cable duct assembly 100.

FIG. 2A illustrates a first hinge mechanism 111. FIG. 4 is an end view illustration of the first cable duct assembly 100 that illustrates a pair of sidewalls 150 (e.g., first sidewall 151, second sidewall 172) connected to the base plate 130. In FIG. 4, the cover plate 110 is hingedly connected to the first sidewall 151 through the first hinge mechanism 111, and the cover plate 110 is hingedly connected to the second sidewall 172 through a second hinge mechanism 121. The hinge mechanisms are formed by the hinged connection between a saddle socket and the arm ends of a sidewall. In aspects, such as is illustrated in FIGS. 1A, 2A, and 4, the hinge mechanisms (e.g., first hinge mechanism 111, second hinge mechanism 121) may generally be identical to one another and, as positioned in the cable duct assembly 100, may be mirror images of each other.

The first hinge mechanism 111 may include the first saddle channel 112 of the saddle socket 118, and the second hinge mechanism 121 may include the second saddle channel 122 of the second saddle socket 120. In other aspects, the first saddle channel 112 is spaced apart from and generally parallel to a second saddle channel 122. The first saddle channel 112 may extend along a length of the cover plate 110 adjacent a first side of the cover plate 110 and the second saddle channel 122 may extend along the length of the cover plate 110 adjacent a second side of the cover plate 110. The first saddle channel 112 and the second saddle channel 122 may be substantially identical and symmetrical. The first saddle channel 112 and the second saddle channel 122 may be disposed on opposed distal edges of the cover plate 110.

The first saddle channel 112 may be configured to snap onto a lobe mechanism 158 of a sidewall 150 (e.g., first sidewall 151). A saddle channel (e.g., first saddle channel 112) can be unsnapped from a mating lobe mechanism (e.g., lobe mechanism 158) to allow the opening of the cover plate 110, which permits the cover plate 110 to pivot about the opposing saddle channel (e.g., second saddle channel 122) that remains attached to the other lobe mechanism on the opposing sidewall (e.g., second sidewall 172) when the saddle channel (e.g., first saddle channel 112) is unsnapped. The base plate 130 and the sidewalls 150 may be separate components, or they may be integrally formed. As is illustrated in FIGS. 1A, 2A, and 4, the sidewalls 150 (e.g., first sidewall 151, second sidewall 172) may generally be identical to one another and, as positioned in the base plate 130, may be mirror images of each other.

FIGS. 8A, 8B, 8C, and 8D illustrate a third cable duct assembly 300 horizontally installed onto a connected vertical surface 8 (connected surface 8). In such a configuration, the base plate 130 is attached to the connected surface 8. The cable duct assembly 300 is illustrated as holding a plurality of cables 2, 3. These Figures illustrate the respective load exerted by the cables 2, 3 on the lower sidewall 151, which causes tension between the cover plate 110 and the sidewall 151, causing the catch portions 190 of the rotation limiters 178 on second arms 174 to engage the cover hook portion 115 of the saddle socket 118, mechanically locking the sidewall 151 to the cover plate 110.

In aspects, this action further causes a movement (rotation) of the cover plate 110 relative to the first hinge mechanism 111 and the second hinge mechanism 121. As illustrated in FIG. 8B, the rotation of the cover plate 110 relative to the first hinge mechanism 111 causes the rotation limiter 179 of an upper second arm 175 to move into engagement with the cover hook portion 113 of the second saddle socket 120 and prevents further rotation of the second hinge mechanism 121. As illustrated in FIG. 8D, the load on the first and second arms of the sidewall 151 may cause rotation of the first pivot connection 133 and brings the snap reinforcement 192 into contact with the inner locking flange 139, thereby locking the sidewall stem 152 within the sidewall connector 132 of the base plate 130.

As illustrated in FIG. 8C, one or more of the cables (e.g., cable 3), may bear against the deflector portion 186 of a second arm 174, which causes the rotation limiters 178 to move into engagement with the cover hook portion 115 of the saddle socket 118 (as illustrated in FIG. 9). As a result, the rotation limiter 178 locks onto the cover hook portion 115 and prevents further rotation of the first hinge mechanism 111.

As a result of the load exerted on the lower sidewall 151, the cable duct assembly 300 moves as a four-bar linkage, with rotation at the first hinge mechanism 111 and the second hinge mechanism 121, and pivots at the first pivot connection 133 and the second pivot connection 135. Through such movement, the cable duct assembly 300 is able to handle the load of the cables 2 without the cover plate 110 detaching or without either of the sidewall stems detaching from its respective sidewall connector.

In FIG. 8D, the load on the sidewall 151 may further cause the outside of the sidewall stem 152 and/or the outside of the lower portion of the sidewall 150 to contact and apply a force to the outer base rail 140 that is translated (transferred) to the base extension 148 and to the connected surface 8. During such a situation, while the outside locking recess 170 may move out of engagement with the outer locking flange 141, the inside locking recess 168 remains engaged with the inner locking flange 139 and the sidewall stem 152 is retained within the locking channel 134, that results in the maintenance of the connection between the sidewall stem 152 and the sidewall connector 132 through pivot connection 133.

The foregoing is considered as illustrative only of the principles of cable duct assemblies, including components therefor.
